Question

Ствол горизонтально расположенного орудия имеет массу 1200 кг . Масса снаряда 10 кг . Скорость снаряда у дульного среза 800 м/с Чему равна скорость отката орудия в момент вылета снаряда

Answer 1

1200+10:800=1,5125 это весь ответ

Answer 2

Calculation of Recoil Velocity

To calculate the recoil velocity of the artillery piece, we can use the principle of conservation of momentum. The formula for the recoil velocity of the artillery piece can be expressed as:

Recoil Velocity (Vr) = (Mass of Projectile * Velocity of Projectile) / Mass of Artillery Piece

Given: - Mass of the artillery piece (m1) = 1200 kg - Mass of the projectile (m2) = 10 kg - Velocity of the projectile (v2) = 800 m/s

Using the conservation of momentum, the recoil velocity (Vr) can be calculated as follows:

Vr = (m2 * v2) / m1

Substituting the given values: Vr = (10 kg * 800 m/s) / 1200 kg

Calculating the recoil velocity: Vr = (8000 kg*m/s) / 1200 kg Vr = 6.67 m/s

Therefore, the recoil velocity of the artillery piece at the moment of the projectile's exit is approximately 6.67 m/s.
